If you find that feeding fish helps you de-stress, especially while you at work, you are in luck. Aquard.io is a web app that allows you to feed real fish using a web app.
Even if you are not exactly a fish person, the app is really cool and provides virtual controls for a real aquarium. You can, for instance, switch camera views or even blow bubbles in the aquarium just for fun. Feeding time comes once in every one hour. So you will have to wait a while before you can see the fish being fed because of your visit.
There is some soothing music in the background, although you have the option to mute it if you are using the app while at work. To see how much time is left until you get to feed the fish, look at the bottom of the screen when visiting the app. It will display the exact number of minutes left in your turn.
For people who are into aquariums or fishes, this is a very cool way of de-stressing and getting a soothing feeling in the middle of a stressful day. All you need to do is browse to the app.
The Acquard.io is also a reminder that there is an increasingly greater number of such apps which deploy virtual controls for real-world scenarios and situations, giving the users a feeling which is very close to reality.
